    • The present invention relates to multiple reflector light or solar energy concentrators and systems using such concentrators using an arrangement of optical elements for the efficient collection of light while minimizing complexities of optics needed to achieve light collection and concentration. The concentrator uses at least three reflectors, in either a dish or trough configuration. A concave primary reflector (20) receives the solar energy and sends it to a secondary convex reflector (30) positioned in the focal zone of the first reflector (20). In turn, the secondary reflector (30) sends the solar energy, at least in part, to a third non-imaging reflector (40) positioned in the focal zone of the secondary reflector (30). In a system (10), a receiver (70) is placed in the focal zone of the third reflector (40). Steam can be generated directly in the receiver (70) when the receiver (70) is in a fixed position.
    • 本发明涉及使用这种聚光器的多个反射器光或太阳能集中器和系统,该集中器使用光学元件的布置来有效地收集光,同时最小化实现光收集和浓缩所需的光学系统的复杂性。 集中器使用至少三个反光镜,以碟形或槽形配置。 凹形初级反射器(20)接收太阳能并将其发送到位于第一反射器(20)的聚焦区域中的次级凸面反射器(30)。 反过来,次级反射器(30)至少部分地将太阳能发送到位于次级反射器(30)的聚焦区域中的第三非成像反射器(40)。 在系统(10)中,接收器(70)被放置在第三反射器(40)的聚焦区域中。 当接收器(70)处于固定位置时,可以在接收器(70)中直接产生蒸汽。

    • One embodiment comprises a parabolic trough reflector including a plurality of mirrors which are configured to reflect sunlight to a lengthwise zone of concentrated solar flux. Each mirror comprises a reflective surface. The mirror surface is defined by a primary curvature within a plane perpendicular to the lengthwise zone of concentrated solar flux. In addition, the reflective surface of one or more of the mirrors comprises a secondary curvature within a plane parallel to the lengthwise zone of concentrated solar flux. The secondary curvature provides for reduced mirror bending deflection under a load, for example, gravity or wind load. Alternative embodiments include systems for generating electricity utilizing a thermal power cycle with thermal energy is provided to a working fluid from concentrated solar flux using parabolic trough reflectors having enhanced mirrors.
    • 一个实施例包括抛物面槽反射器,其包括多个反射镜,其被配置为将太阳光反射到集中的太阳能通量的纵向区域。 每个反射镜包括反射表面。 镜面由垂直于浓缩太阳能通量的纵向区域的平面内的主曲率限定。 此外,一个或多个反射镜的反射表面包括平行于浓缩太阳能通量的纵向区域的平面内的次曲率。 次级曲率提供了在负载(例如重力或风荷载)下减少镜子弯曲偏转。 替代实施例包括使用具有热能的热能循环发电的系统,其通过使用具有增强反射镜的抛物线槽反射器从集中的太阳能通量提供给工作流体。

    • A device for gaining solar energy comprises a integral unit with a casing (10..13). The casing comprises reflection means (20) with a hollow reflector surface (25) and is closed off by refraction means (30) with an entry surface (35) for entering sunlight. The refraction means and reflection means are each rotatably arranged around a rotation axis (71, 72) and their orientation relative to each other is continuously adjusted to the current position of the sun in the sky using positioning means provided for that purpose. The casing comprises a number of dustproof, but nevertheless ventilating chambers. The first chamber (100) is situated between the refraction means (30) and the reflection means (20) and comprises energy-conversion means (40) at least near to the focal point of the reflector surface (25). A second chamber (200) is situated between the reflection means (20) and the base part (13) of the casing and comprises positioning means (51, 53) for rotating the refraction means (30) and the reflection means (20).
